What material is typically visible when a pole strap is worn?

When a pole strap is worn, it is designed to be easily identifiable for safety and operational purposes. The visible contrasting color serves a critical function by enhancing visibility, which aids in quick identification by the users and contributes to overall site safety. A contrasting color can also indicate the condition or specific attributes of the strap, making it easier for workers to determine if it is fit for use.

While options such as worn-out string, metal backing, and plastic casing may be components of other safety or attachment devices, they do not serve the same clear visibility purpose that the contrasting color provides on a pole strap. The emphasis on visibility is key to ensuring that workers can spot safety equipment quickly, especially in dynamic or low-visibility environments.
